Flutter After Upgrade can't run application version solving failed

Question

Nope. This answer doesn't work this time for me.

My flutter doctor -v

When I run flutter run, I get:

Running "flutter packages get" in townsquare...                  
The current Dart SDK version is 2.1.0-dev.0.0.flutter-be6309690f.

Because flutter_circular_chart 0.0.3 requires SDK version >=1.19.0 <2.0.0 and no versions of flutter_circular_chart match >0.0.3 <0.1.0, flutter_circular_chart ^0.0.3 is forbidden.
So, because mobile depends on flutter_circular_chart ^0.0.3, version solving failed.

pub get failed (1)

This is my pubspec.yaml

name: mobile
description: A new Flutter project.

version: 1.0.0+1

dependencies:
  flutter:
    sdk: flutter

  cupertino_icons: ^0.1.2
  carousel: ^0.0.1
  http: "^0.11.3+16"
  validate: "^1.6.0"
  url_launcher: "^3.0.2"
  shared_preferences: "^0.4.2"
  font_awesome_flutter: "^7.0.0"
  flutter_circular_chart: "^0.0.3"
  flutter_local_notifications: ^0.3.6

dev_dependencies:
  flutter_test:
    sdk: flutter

  assets:
   - images/flutter.jpg
   - images/logo.png
   - images/bg_viewer.jpg

With the above, please enlighten me, what's wrong?

That's is because you are using : Dart version 2.1.0-dev.0.0.flutter-be6309690f and the plugin named flutter_circular_chart has a constraint

https://github.com/xqwzts/flutter_circular_chart/blob/master/pubspec.yaml

environment:
   sdk: '>=1.19.0 <2.0.0'

You can fork the project and update the sdk constraint and ref to your repository:

Like this:

flutter_circular_chart:
    git: https://github.com/your_repo/flutter_circular_chart.git

Note Also would be fine if you open an issue in their repo to notify the devs about the issue that you have.

What about multiple plugins dependency?... one cant be forking every repo in order to modify them...

diegoveloper Over a year ago

yeah that is something that plugin developers have to take in mind, I mean keeping the plugin updated or the community could help with it.

Use devendency_override with same version witch need for same for other dependency.

Like google_maps_flutter: ^0.5.28+1 needs intl to be 0.16.0

then craete dependency_overrides: intl: ^0.16.0

below of dev_dependencies: flutter_test: sdk: flutter

run project until it not run on device.

Enjoy. Thanks..
